Error Message Today
So this popped up while driving today. Felt like it went into limp mode. No noises or any issue I could feel. Got home. Shut it down then restarted it, warning went away and drove fine. 60k miles all service to date. Ideas?
edit: took it out again. filled up tank, got on highway, full acceleration... noticeably down on power then error message came back.

I noticed that you have a Dinan Stage 1. I have a Stage 2 and the same thing happened to me. If you have access to the Dinan app, put it in bypass mode, clear the codes, and see if it comes back. If it doesn't then contact Dinan. For me, the warning would come on again after about 100 miles with the tune on.

It may also be a good idea to check the fluid level for the charge cooler. Maximum power may not be available because the cooler could be low on fluid, which means the intake charge air is crazy hot.

Just checked it and it was very low. topped it off. will take for a drive and report back. I shouldn't be losing coolant though correct? Going to drop it off at my shop just the same. Thanks for the feedback guys.

Yep, definitely leaking. It frequently leaks fluid into the intake runners (where it is then burned by the engine), so it may not be noticeable externally. If it leaks badly enough, there is a risk (albeit really low) that the engine could hydrolock. |

hey thanks for the feedback .. here's an update. Took it to my shop. they ran the codes. Def the coolant level for the charge cooler (not sure if there was work done on it before I bought the car recently). so we topped it off. Ran the car again, car ran fine. However, per their instructions, I let it cool off and checked again.
It was low. As I was topping it off the level kept dropping a bit. Had to actually wait and top it 3x. Took it for a drive again. Letting it cool off.. I'll check level again later. This time I noticed the charge cooler was not scorching hot, warm, but able to keep my hand on it. So basically I'm going to keep it an eye on it next few drives. Obviously if it keeps getting low then my shop will look into it further. They've been nothing but helpful so far (reputable BMW shop in North Jersey.) Will keep updating post. Quote:

Do not keep adding coolant and stay out of boost. When you replace the cooler make sure to change the oil before anything else.

Just an update. Since last I posted I've driven it a few times just to keep monitoring levels. And the level has not dropped since. Been holding steady at max level. Haven't needed to top off at all. Will keep monitoring. Maybe air in the system? Don't know.
In the meantime I have an appt scheduled at my shop just the same.
